How to get phone location of iPhone

How can I get the location of a user, or a phone device, or the location of the phone that started the flow?

I want to estimate the ETA to home, based on the phone location. there are many apps to do this, but they assume you already know the location. I cannot find how to get the iOS iPhone location. how can I do this?

If you only need the traveltime: with ‘opdrachten’ you can have ‘kaarten’ calculate the traveltime and send this time as tag in a webhook to homey.

This app shows travel time to home for iPhones. You have to be careful with battery drainage but there are ways to tweak that on the config

But this means you have to start the from opdrachten, but I would like to start it from a homey flow if possible.

this app does nog provides you with your current location right?

Correct.
